My wife and I process ours. We used an old hand grinder the 1st time. What a pain. She has one of those heavy stand mixers that have bread hooks and all. If you or your wife has one, you can purchase a meat grinder attachment for like $50. We used a vacuum sealer and pre-marinated the steaks before vacuum sealing and freezing. Worked great.

We mixed 1/3 pork fat in with our ground. Was great for chilli, spaghetti, whatever.
